A shuttlecraft is initially moving at 96.0 m/s as it travels in
deep space. The mass of the shuttle given its current fuel level is
approximately 6.41 ✕ 106 kg. When the
shuttle fires its rockets to move faster, the speed of the exhaust
leaving the rockets is 2900 m/s. What is the mass of the fuel
necessary to get the shuttlecraft up to a final speed of 130 m/s?

A cart is moving horizontally along a straight line with constant speed 30 m/s.
Problem 12:A cart is moving horizontally along a straight line with constant speed 30 m/s. A projectile is to be fired from the moving cart in such a way that it will return to the cart after the cart has moved 80m. At what speed (relative to the cart) and at what angle (to the horizontal) must the projectile be fired?NOTE: remember that to calculate the speed of the projectile respect to the cart, we need to subtract the velocity...
